Backup Cal Data To Motherboard Memory

This adjustment is an operation that backs up the entire file system and all calibration data to the motherboard memory. It is optional and does not have to be run. The user may choose to run this adjustment to backup calibration data after other adjustments have succeeded.

These are some suggested use conditions:

When to backup:

• After a successful adjustment of the product. Adjustments are successful if the product passes all performance tests.

When not to backup:

• If adjustments have not completed or if performance tests do not pass.

  Performing a backup under these conditions will overwrite factory defaults which cannot be recovered by the user.

When to restore from backup:

• To restore the product to a known good state after attempting, but failing to successfully run adjustments.
• The restore routine can be accessed from the front panel by pressing: Utility --> Instrument Adjustments -->Service Adjustments --> Restore System Files.

Refer to the Service Guide for related information.
